21) Sunrise over Kettle Peak on the way to Ehrnbeck; early starts are mandatory, since participants return to the trailhead after each peak and move on to the next day’s challenge, sleeping in campgrounds or hotels in between.
22) Jantz leads a 5 a.m. start.
23) The scree field on Buck Mountain slowed the ascent, but going down was really fast.
24) Burd, seen here on the way to Tamarack Peak, is the only hiker who has done the Sierra Challenge every year. He’s managed all 10 peaks seven times. Burd took home both the Yellow and Green Jerseys in 2011 (for 2012, he’s raising the age of the masters class to make himself ineligible). Three others—Tom Grundy, Adam Jantz, and Bill Peters, 38—summited all of the peaks as well. At 25, Jantz missed winning the White Jersey by one year (no one claimed it in 2011). Reports of times and climbs are on the honor system.
